本文对中国英语二语学习者和美国英语母语者英语词重音声学特征进行对比实验,意在探讨目的语国家的学习经历的有无对被试英语词重音的声学特征的影响程度。实验结果表明:(1)有目的语国家学习经历者在音长和音强的语音声学特征上更接近于英语发音模式,但仍与英语模式有差异。(2)有目的语国家学习经历者和无目的语国家学习经历者的首音节为词重音的音高模式同英语发音模式具有相似性,而其末音节为词重音的音高模式同英语发音模式具有差异性。(3)目的语国家的学习经历可改变学习者对英语词重音位置的语音倾向性。
This paper compares the accent characteristics of English word stress between L2 learners in China and native English speakers in the United States to explore the impact of learning experience in target countries on the acoustic characteristics of English word stress. The experimental results show that: (1) learners with target language learning experience are closer to the English pronunciation pattern in the phonetic and acoustic characteristics of the sound length and sound intensity, but still have differences from the English patterns. (2) The pitch pattern of the first syllable with the learning experience of the target country and the learner of the non-target language is similar to the English pronunciation pattern, while the last syllable is the pitch pattern of the word accented with English pronunciation Patterns are different. (3) The learning experience of the target language countries can change the learner’s phonological tendencies of English word stress.
